In the expression, the unknown values are
y = 7
x = 2
How to solve for x and y
According to the problem we have the expression as follows
- b) 13y + 19 = 6(9 + y) + 14
- d) 8x - 2(x + 5) = 2(x - 1)
Solving for y
13y + 19 = 6(9 + y) + 14
open the parenthesis by multiplying by 6
13y + 19 = 54 + 6y + 14
Collect like terms
13y - 6y = 54 + 14 - 19
Isolate y by dividing through by 7
7y = 49
y = 7
Solving for x:
8x - 2(x + 5) = 2(x - 1)
open the parenthesis by multiplying by 6
8x - 2x - 10 = 2x - 2
Collect like terms
8x - 2x - 2x = - 2 + 10
Adding up
4x = 8
Isolate x by dividing through by 4
x = 2
