3x+2y = 23 5x+2y = -17 solving systems of equations by eliminations

Subtract the 2nd row from the 1st row

-8x = 40

Solve for x in the equation above

x = -5

Substitute x = -5 into any of the two equations above. Let's pick the first equation; -3x + 2y = 23

-3 × -5 + 2y = 23

Solve for y in the above equation

y = 4

Therefore,

x = -5

y = 4

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
