Answer:
C = ¼(4B – 7A)
Step-by-step explanation:
⁴/₇(B – C) = A Multiply each side by 7
4(B - C) = 7A Remove parentheses
4B – 4C = 7A Subtract 4B from each side
-4C = 7A – 4B Multiply each side by -1
4C = -7A + 4B Divide each side by 4
C = ¼(4B – 7A)
Answer: x=2
Step-by-step explanation:
Given
9(x+1)=25+x
Distributive property
9x+9=25+x
Subtract x on both sides
9x+9-x=25+x-x
8x+9=25
Subtract 9 on both sides
8x+9-9=25-9
8x=16
Divide 8 on both sides
8/8 x=16/8
x=2
