Answer:
x = 24
y = 15
Step-by-step explanation:
we know that (6x - 7) + (3x - 29) = 180 ---- eq. 1
8y + 17 = 6x - 7 -------- eq. 2
find: x and y
solution:
solve x using eq. 1
- (6x - 7) + (3x - 29) = 180 combine similar terms
- 6x + 3x = 180 + 7 + 29
- 9x = 216
- x = 216 / 9
- x = 24
substitute x = 24 into eq. 2
- 8y + 17 = 6x - 7
- 8y + 17 = 6(24) - 7
- 8y = 114 - 7 - 17
- y = 120/8
- y = 15
