Answer:
8x = 24
Step-by-step explanation:
Solve for x:
4 x + 3 = 15
Subtract 3 from both sides:
4 x + (3 - 3) = 15 - 3
3 - 3 = 0:
4 x = 15 - 3
15 - 3 = 12:
4 x = 12
Divide both sides of 4 x = 12 by 4:
(4 x)/4 = 12/4
4/4 = 1:
x = 12/4
The gcd of 12 and 4 is 4, so 12/4 = (4×3)/(4×1) = 4/4×3 = 3:
Answer: x = 3 now multiply 8x = 8*3 = 24
