twenty-four
Solve the equation (x+2)×15=(x-3)×18
15x+15×2=18x-18×3
18x-15x=30+54
3x=84
x=84÷3
x=28
Is that ok?
3 × 18 + x = 90 to solve the equation
3×18+×=90
54+×=90
×=90—54
×=36
Solution equation: 2.6 + 3.2 (6-x) = 18
3(x-6)²=2(6-x)
3(x-6)²+2(x-6)=0
(x-6)(3x-18+2)=0
(x-6)(3x-16)=0
x-6=0 3x-16=0
x1=6 x2=16/3
