3x - 2y = 5
-2x + 2y = -2
--------------------add
x = 3
3x - 2y = 5
3(3) - 2y = 5
9 - 2y = 5
-2y = 5 - 9
-2y = -4
y = -4/-2
y = 2
solution is (3,2)
ur system of equations is : 3x - 2y = 5 : -2x + 2y = -2

Step-by-step explanation:
Simplifying
n + -16 = m
Reorder the terms:
-16 + n = m
Solving
-16 + n = m
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '16' to each side of the equation.
-16 + 16 + n = 16 + m
Combine like terms: -16 + 16 = 0
0 + n = 16 + m
n = 16 + m
Simplifying
n = 16 + m
Answer:
48
Step-by-step explanation:
Wrong : right
1 :12
Multiply by 4 because she gets 4 problems wrong
1*4 : 4*12
4 :48
If she gets 4 problems wrong, she gets 48 problems right
