Answer:
x = -3
y = 4
Step-by-step explanation:
distribute first
7x + 35 = 2y + 6
combine 'like terms'
7x - 2y = -29
do same steps for second equation
4x + 4y = 13 + 3x
x + 4y = 13
System of Equations:
7x - 2y = -29
x + 4y = 13
Multiply the first equation by 2 to eliminate the 'y-term'
14x - 4y = -58 (Now add this to the second equation)
+ x + 4y = 13
15x = -45
x = -3
Substitute -3 for 'x' to find 'y'
-3 + 4y = 13
4y = 16
y = 4
