Question

3x+5x+96=1568


357z-149z-1843=11469


2y+7y+78=1581

Answer 1

3x+5x+96=15688х= 1568 - 96
8х= 1472
х= 1472/8
х= 184

357z-149z-1843=11469
208z =11469+ 1843
208z= 13312
z= 13312 /208
z=64


2y+7y+78=1581
9y= 1581- 78
9y=1503
y= 1505/9
y=167

Answer 2

3x+5x+96=1568
8x= 1568-96
8x=1472
x=1472:8
x=184



357z-149z-1843=11469
208z=11469+1843
208z=13312
z=13312:208
z=64
