solving multi-step equations

4x - 3x =-7

and

5 = 1 - 2a + a

write out each and show your work!

x=−7

5=−a+1

Steps

So, we have

4x−3x=−7

Step 1: Simplify both sides of the equation.

4x−3x=−7

4x+−3x=−7

(4x+−3x)=−7(Combine Like Terms)

x=−7

So, we have

5=1−2a+a

Step 1: Simplify both sides of the equation.

5=1−2a+a

5=1+−2a+a

5=(−2a+a)+(1)(Combine Like Terms)

5=−a+1

x=-7

a=-4

Step-by-step explanation:

4x-3x=-7 Original Equation

x=-7  Combine like terms

5=1-2a+a

5=1-a  Combine like terms

4=-a  Subtract 1 on both sides

a=-4  Divide -1 on both sides to get rid of the negative
