Question

Solve each system of equations using any method.
y = 5x +7
y = 4x - 3

Answer 1

x = -10 and y = -43 so the correct answer would be (-10,-43)

Answer 2

x= -10

y= -43

Explanation:

since both of your equations equals y just plug it into each other and than make the equation: 5x+7=4x-3

and than you can just start with the variables OR numbers and then simplify

5x+7=4x-3

5x+10=4x

10= -x

x= -10

so -10 for x

plug it in to one of your 2 equations to get y

5(-10)+7= y

-50+7=y

y= -43
