Answer:
x = -11.5;. y = -58.5
Step-by-step explanation:
-3x+y=-24
y=7x+22
-3x+(7x+22)=-24
-3x+7x+22=-24
4x=-24-22
4x = -46
x = - 11.5
y= 7 * (-11.5) + 22
y = -58.5
Answer:
first one: 8
second one: 3
Step-by-step explanation:
-3x + y = -24 |÷(-3x)
y = 8
y = 7x + 22 |-y
(y would be 1; the 7x moves to the other side.) meams:
7x = 21 |÷7
x = 3
