Answer:
x = 4
Step-by-step explanation:
3x -5 = -2 + 9
-2 + 9 = 7 so now its 3x - 5 = 7
add 5 to the -5 so it cancels itself out. then add the 5 to 7 so it become 12. the you have 3x = 12
divide 12 ÷ 3 = 4
x = 4

A. 12y+45
Answer:
y= -1; x=5
Step-by-step explanation:
Replace the x in the first equation with x=1-4y
2(1-4y)+7y=3
2-8y+7y=3
-y=1
y= -1
x=1-4(-1))
x=5
