How To Solve Algebra 1 Problems

You can say that we put everything else on the other side of the equal sign.It is always a good idea to first isolate the terms including the variable from the constants to begin with as we did above by subtracting or adding before dividing or multiplying away the coefficient in front of the variable.If you said 5x equals 20, instead of dividing by 5, we could multiply by 1/5.

Once you have finished, press "finish" and you get a table with your answers and the right answers to compare with.

So at first this might look a little unfamiliar for you, but if I were to rephrase this, I think you'll realize this is a pretty easy problem.

And the right hand side, 20 divided by 5 is 4, and we would have solved it.

Another way to do it, and this is actually the exact same way, we're just phrasing it a little different.

in the example below there are more x:es on the left side (4x) compared to the right side (2x) and hence we collect all x:es on the left side.

Example $x 3 =2x 11$$ subtract 2x from both sides $x 3\, =2x 11\, $$ Now it looks like any other equation $x 3=11$$ subtract 3 from both sides $x 3\, =11\,$$ $x=8$$ Divide by 2 on both sides $$\frac=\frac$$ $$x=4$$ In the beginning of this section we showed the formula for calculating the velocity where velocity (v) equals the distance (d) divided by time (t) or $$v=\frac$$ If we by some chance want to know how far a truck drives in 3 hours at 60 miles per hour we can use the formula above and rewrite it to solve the distance, d.

The left hand side, the minus 4/3 and the 3/4, they cancel out.

You could work it out on your own to see that they do.

$$\frac\, =v\,$$ $$d=v\cdot t$$ When that's done we can just put our numbers in the formula and calculate the answer $$d=60\cdot 3=180$$ The truck travels 180 miles in 3 hours.

You can review your answers and change them by checking the desired letter.

    Solve ; The variable in this equation is already on one side of the equation by itself. There is no need to add or subtract anything to both sides. However, the number in front of the variable is not 1. The -3 that is in front of the variable indicates multiplication of -3 by x. The opposite operation of multiplication is division. So we will.…
