Answer: Solution:
7x=-49
Step-by-step explanation:
4x-3y=8→(1)
5x-2y=-11→(2)
equation(1)×2⇒8x-6y=16
equation(2)×3⇒15x-6y=-33
Substracting ⇒-7x=49

Answer:
(-2,1)
Step-by-step explanation:
Answer:
(2,2)
Step-by-step explanation:
Given equations
x-3y=-4-------------------------------(1)
y=-3x+8.------------------------------(2)
Substitute 2 in 1. This means use the value of y in equation 1, to replace y
x-3(-3x+8)=-4------------------open brackets
x+9x-24=-4---------------------collect like terms
10x=-4+24
10x=20---------------------------divide by 10 both sides to get value of x
10x/10=20/10=2
x=2------------------------------use value of x in equation (2) to get value of y
y=-3x+8
y=-3(2)+8
y=-6+8=2
solutions
x=2, y=2
