Question

-0.3(x-4)+x=0.5(3-x)

Answer 1

-0.3(x-4)+x=0.5(3-x)
distribute both sets
-.3x -.12 +x = -2.5 -.5x
combine like terms
.7x -.12 = -2.5 -.5x
isolate variable on one side by adding.5x to both sides
1.2x - .12 = -2.5
isolate variable completely by adding .12 to both sides
1.2x = -2.38
divide both sides by 1.2
x = -1.9833 (33 goes on forever)

Answer 2

plug answer in for x to verify that both sides equal the same number in the end...which is called a balance statement

Answer 3

-0.3x + 1.2 +x =1.5 -0.5x
0.5x -0.3x + x = 1.5 -1.2
1.2x = 0.3
