Question

C. 3x-7=2x-5 solve for x, simplify

Answer 1

x=2

Explanation:

addition property of equality is adding the same number to both sides of an equation does not change the equation.

subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.

distributive property: a(b+c)=ab+ac

add 7 both sides of an equation.

3x-7+7=2x-5+7

simplify.

3x=2x+2

subtract 2x both sides of an equation.

3x-2x=2x+2-2x

simplify.

x=2

Hope this helps!

Thanks!

Answer 2

3x - 7 = 2x - 5 add 7 to both sides

3x = 2x + 2 subtract 2x from borh sides

x = 2

Check:

L = 3(2) - 7 = 6 - 7 = -1

R = 2(2) - 5 = 4 - 5 = -1

L = R CORRECT! :)
