Question

Solve the system of equations
Y = -3× + 2
× - 2y= 10

Answer 1

y = -3x + 2 ***Given***
x-2y = 10 ***Given***

x - 2(-3x +2) = 10 ***Substitute y in one equation into the other***
x + 6x - 4 = 10 ***Simplify by distribution***
7x = 14 ***Solve for x***
x = 2

y = -3(2) + 2 ***substitute x into other equation and solve for y***

x = 2
y = -4
