Answer:
x = - 9/10
workings
2/3 x = - 3/5
multiply by 3/2 on both sides
x = - 9/10
Answer:
x=9 y=-4
Step-by-step explanation:
1) to eliminate a variable make sure they are the same so you can cancel them out
lets eliminate x
-3 and -2 share a GCF of 6 so
2(-3x-4y=-11)
-6x-8y=-22
3(-2x-6y=6)
-6x-18y=18
-6x-8y=-22
-
-6x-18y=18
--------------------------
10y=-40
y=-4
2)substitute y as -4 in the second equation
-2x-6(-4)=6
-2x+24=6
-2x=-18
x=9
