Answer:
x = 1/9.
Explanation:
-4(2x - 5) – (7 – 3x) = 4(x + 3)
-8x + 20 - 7 + 3x = 4x + 12
-8x + 3x - 4x = 12 + 7 - 20
-9x = -1
x = 1/9.

Answer:
y = 2
x = 5
Step-by-step explanation:
4x + 5y = 10 | ×3 |
3x - 3y = 21 | ×4 |
12x + 15y = 30
12x - 12y = 84
____________--
27y = -54
y = -54/27
y = 2
4x + 5y = 10 | ×3 |
3x - 3y = 21 | ×5 |
12x + 15y = 30
15x - 15y = 105
____________+
27x = 135
x = 135/27
x = 5
