Answer:

x = 15/2 or x = 7.5

Step-by-step explanation:

Step 1: Write equation

3(x + 4) = 7x - 18

Step 2: Solve for <em>x</em>

<u>Distribute 3:</u> 3x + 12 = 7x - 18

<u>Subtract 3x on both sides:</u> 12 = 4x - 18

<u>Add 18 on both sides:</u> 30 = 4x

<u>Divide both sides by 4:</u> x = 15/2 or x = 7.5

1)B -26-27x
steps :distribute ,-9 times 3 =-27 , -9 times 3x = -27x , now combine like terms :you have a 1 and a -27 ,1-27=-26,and you left with -27



2)D 11-49x
steps :distribute , positive 7 times 1= 7 and then positive 7 times negative 7x =-49, now combine like terms ,since you have a positive 4 combine it with positive 7 which is 11 and finally put it together with -49x which it would look like 11-49x
