Answer:
Step-by-step explanation:
for the 1st one you multiply 2+2 by 2 the answer is 8 i cant see the whole 2nd problem so I dont know
Answer:
x=9
Step-by-step explanation:
4x+2=7x-25(being vertically opposite angles)
2+25=7x-4x
27=3x
27/3=x
9=x
Answer: x = 5, y = 7
Step-by-step explanation:
First, put the variables together/rearrange:
y - x = 2 & 5x - 4y = -3
Cancel out variable x by multiply the first equation by 5:
5y - 5x = 10 & 5x - 4y = -3
Add equations:
y = 7
Then determine x by plugging y back into the first equation y = x + 2:
x = 5
