Question

Using algebra, what is the first step in solving the following equation for the value of x;

8x + 12 = 52.

a) perform the inverse of multiplying by 8 (divide by 8) b) subtract 12 to form the identity (0) and cancel the 12. c) using the property of equality and do the same thing on both sides of the equal sign.
d) isolate the variable

Answer 1

×=5

Explanation:

-12 both sides

then divide 8 both sides

40/8 =5

Answer 2

subtract 12 to form the identity (0) and cancel the 12.

Explanation:

Subtract 12 from both sides.

8x=52−12

2 Simplify 52-1252−12 to 4040.

8x=40

3 Divide both sides by 88.

x=\frac{40}{8}

40/8

simplify 40 over 8 to 5

x=5
