x=-1, y=-1

Step-by-step explanation:

Let's solve your system by substitution.

−3x+y=2;7x−8y=1

Step: Solve−3x+y=2for y:

−3x+y=2

−3x+y+3x=2+3x(Add 3x to both sides)

y=3x+2

Step: Substitute3x+2foryin7x−8y=1:

7x−8y=1

7x−8(3x+2)=1

−17x−16=1(Simplify both sides of the equation)

−17x−16+16=1+16(Add 16 to both sides)

−17x=17

−17x /−17

= 17 /−17

(Divide both sides by -17)

x=−1

Step: Substitute−1forxiny=3x+2:

y=3x+2

y=(3)(−1)+2

y=−1 (Simplify both sides of the equation)

x=−1 and y=−1

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
