Answer

x = -60.2

Work Step by Step

7(x+8.6)=6x Use the distributive property 7x+ 7$\times$8.6 =6x 7x + 60.2 =6x Subtract 60.2 from both sides 7x + 60.2 -60.2=6x -60.2 7x = 6x - 60.2 Subtract 6x from both sides 7x -6x = 6x - 60.2 -6x x=-60.2 Check Replace x with -60.2 7(x+8.6)=6x 7(-60.2+8.6)=6(-60.2) 7(- 51.6)=-361.2 -361.2=-361.2
