Question

PLS HELP SOLVE THESE TWO

Answer 1

1. 150

2.160

Explanation:

1.

or, (x-10)+40+x/3+(x-20) = 360

or, x-10+40+x/3+x-20=360

or, 2x+x/3+10=360

or, (3*2x+x)/3=350

or, (6x+x) = 1050

or, 7x=1050

or, x=150

2.

or, x/2+x-15+100+x/2+x-25=540

or, x/2+x/2+2x+60=540

or, 2x/2+2x=540-60

or, ×+2x=480

or, 3x=480

or, x=160
