Question

solve for x and y: 2x-6/y=1 and 3x+2/y=7​

Answer 1

Step-by-step explanation:

Equation 1: x - y = -10

Equation 2: 2x + 3y = 15

Equation 1, Rearranged: y = x + 10

Equation 1 Substituted into 2: 2x + 3(x + 10) = 15

Equation 1 Substituted into 2: 2x + 3x + 30 = 15

Equation 1 Substituted into 2: 5x + 30 = 15

Equation 1 Substituted into 2: 5x + 30 - 30 = 15 - 30

Equation 1 Substituted into 2: 5x = -15

Equation 1 Substituted into 2: x = -3

Equation 1, Solve for Y: 2(-3) + 3(y) = 15

Equation 1, Solve for Y: -6 + 3y = 15

Equation 1, Solve for Y: 3y = 21

Equation 1, Solve for Y: y = 7

Solution: x = -3, y = 7
