Question

3x+5=8x-15
3x+16=8x-9
4+25y=6+24y
4(x-3)-16=5(x-5)
5x+27=4x+21

Answer 1

3x+5=8x-15         
3X-8X=-15-5
-5X=-20
X=-20/-5
X=-4


3x+16=8x-9
3X-8X=-9-16
-5X=-25
X=-25/-5
X=-5


4+25y=6+24y
25Y-24Y=6-4
Y=2


4(x-3)-16=5(x-5)
4X-12-16=5X-15
4X-5X=-15+12+16
X=43


5x+27=4x+21
5X-4X=21-27
X=-6
