Answer:
- 43t - 22s - 3
Step-by-step explanation:
(–45t + 53s) + (–3 – 75s + 2t)
Opening the brackets
-45t + 53s -3 - 75s + 2t
Collecting like terms
-45t + 2t + 53s - 75s -3
Simplify the expression
-43t -22s - 3
Solve for y for both equations then equate and solve:
5x + 9y = 160
9y = 160 - 5x
y = 160/9 - 5/9x
9x + 8y = 202
8y = 202 - 9x
y = 202/8 - 9/8x
160/9 - 5/9x = 202/8 - 9/8x (common denominator is 72)
1280/72 - 40/72x = 1818/72 - 81/72x
1818/72 - 1280/72 = 81/72x - 40/72x
538/72 = 41/72x
538 = 41x
538/41 = x
x = 13 5/41
