Answer 1

4(x + 3) = 5(x - 2)

4х + 12 = 5х - 10

х = 22

=================================

6 -2(x - 5) + 3(x - 4) = 4x + 1

6 - 2х + 10 + 3х - 12 = 4х + 1

3х = 3

х = 1

=================================

3(x - 1) = 2(x + 2)

3х - 3 = 2х + 4

х = 7

=================================

3(x - 5) - 2(x + 4) = -5x + 1

3х - 15 - 2х - 8 = - 5х + 1

6х = 24

х = 4
