2. Solve the equation. *
-12(x - 12) = -9(1 + 7x)

Use the distributive property to multiply -12 by x-12.

Use the distributive property to multiply -9 by 1+7x.

Add 63x to both sides.

Combine -12x and 63x to get 51x.

Subtract 144 from both sides.

Subtract 144 from -9 to get -153.

Divide both sides by 51.

Divide -153 by 51 to get -3.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4
