Step-by-step explanation:
Answer:
x = 11, y = 9
Step-by-step explanation:
Given the 2 equations
x + y = 20 → (1)
3x - 3 = 30 → (2)
In (2) add 3 to both sides
3x = 33 ( divide both sides by 3 )
x = 11
Substitute x = 11 into (1)
11 + y = 20 ( subtract 11 from both sides )
y = 9
–4(6x + 3) = -12<span>(x + 10)
</span><span> -24x - 12 = -12x - 120
12x = 108
x = 9
