Answer:
x = 1/2 = 0.5
Step-by-step explanation:
We must solve x in the following equation:
–3x + 1 + 10x = x + 4
We'll try to get the terms with x on the left and the independent terms on the right by performing the opposite operations on both sides of the equation:
–3x + 1 + 10x -x = x + 4 -x
–3x + 1 + 10x -x -1 = 4 -1
6x = 3
Now lets isolate x, again by performing the opposite operation, that is dividing by 6 on both sides:
6x /6 = 3/6
x = 1/2 = 0.5
