Question

Necesito resolver las ecuaciones 5x(2x—3) —6=4x+3 11x—15=12+2x 3(x—2)+x=5(x—3)+9

Answer 1

5×(2x-3)-6 = 4x+3
10x-15-6 = 4x+3
10x-21 = 4x+3
10x+4x = 3+21
6x = 24
x = 24÷6
x = 4

11x-15 = 12+2x
11x-2x = 12+15
9x = 27
x = 27÷9
x = 3

3(x-2)+x = 5(x-3)+9
3x-6+x = 5x-15+9
4x-6 = 5x-15+9
-6+15-9 = 5x-4x
0 = x
