Answer: 448
Step-by-step explanation:
X-5y=36
x+y=-26
y=-26-x
x-5(-26-x)=36
x+130+x=36
2x+130=36
2x=36-130
2x=-94
x=47
The third one should be -2(2x-6)=12-4x
Last one should be 2(2x-6)+4x=8x-12
Answer:
yes
Step-by-step explanation:
in 13, both x and y are increasing by 1 correspondingly, and, in 14, both sides are multiplying by 2 together.
