Answer:
(2,3)
Step-by-step explanation:
- Substitute the equation for y instead of the y variable.
-3x - 2(5x - 7) = -12
-3x - 10x + 14 = -12
-13x = -26
x = 2
- Now substitute the value of x into the other equation.
y = 5x - 7
y = 5(2) - 7
y = 10 - 7
y = 3
Answer:
x = 2 and y = 3
Step-by-step explanation:
y = 5x - 7
-3x - 2y = -12
Substitute y into the second equation:
-3x - 2(5x-7) = -12
Simplify:
-13x = -26
x = 2
Substitute x into the first equation:
y = 5(2) - 7
y = 10 - 7
y = 3
