2.5(x-3)+1.7x=10.8(x+1.5)
2.5X-7.5+1.7X=10.8X+16.2
2.5X+1.7X-10.8X=16.2+7.5
-6.6X=23.7
X=23.7/-6.6 OR -23.7/6.6 ANS.
PROOF:
2.5(-23.7/6.6-3)+1.7*-23.7/6.6=10.8(-23.7/6.6+1.5)
2.5[(-23.7*-3*6.6)/6.6]-40.29/6.6=10.8[(-23.7+1.5*6.6)/6.6]
2.5[-23.7-19.8)/6.6]-40.29/6.6=10.8[(-23.7+9.9)/6.6]
2.5[-43.5)/6.6]-40.29/6.6=10.8[-13.8/6.6]
-108.75/6.6-40.29/6.6=-149.04/6.6
149.04/6.6=149.04/6.6
