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

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

Step-by-step 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

×=5

Step-by-step explanation:

-12 both sides

then divide 8 both sides

40/8 =5

depends on how many days you are talking about

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
