Problem# 39: Solve for C: 1/2(c+8)=1/4c

Problem# 41: Solve for A:

Problem# 39:
Solve for C:

:
Get rid of the denominator, multiply equation by 4:
4* = 4*
:
Cancel out the denominators and you have;
2(c+8) = 1c
2c + 16 = c; multiply what's inside the brackets
2c - c = -16; subtract c and 16 from both sides
c = -16
:
Check solution by substitution in original equation:

-4 = -4

Problem# 41: Solve for A:

;
Multiply equation by 5 to get rid of the denominators:
5* + 5(8) = 5*
:
1a + 40 = -3(a-15)
a + 40 = -3a + 45
a + 3a = 45 - 40
4a = 5
a = 5/4

:
Check solution using 1.25 as 5/4:

:
.25 + 8 =
8.25 = 8.25 confirms out solution
