5(3-2y)-4(9-y)=3(y+5) 9(3x-7)+3(8x-11)=3(9x+8)

Question

5(3-2y)-4(9-y)=3(y+5)
9(3x-7)+3(8x-11)=3(9x+8)

Answer 1

5(3-2y)-4(9-y)=3(y+5)
15-10y-36+4y=3y+15
-6y-3y=15-15+36
-9y=36
   y=-4

9(3x-7)+3(8x-11)=3(9x+8)
27x-63+24x-33=27x+24
24x=24+96
24x=120
x=5

Answer 2

1)5(3-2y)-4(9-y)=3(y+5)
15-10y-36-4y=3y+15
10y-4y-3y=-15+36+15
3y=36
y=36:3
y=12
2)9(3x-7)+3(8x-11)=3(9x+8)
27x-63+24x-33=27x+24
27x+24x-27x=63+33+24
24x=120
x=120:24
x=5
