Distribute 1/2 throughout the set of parenthesis
1/2 · x = 1/2x
1/2 · 12 = 6
1/2x + 6 = 4x -1
subtract 6 on both sides of the equation
1/2x = 4x - 7
subtract 1/2x by 4x
4x - 1/2x = 7/2x
7/2x = -7
isolate x by dividing both sides by 7/2
Which is actually multiplying by the reciprocal, which is 2/7
-7 · 2/7 = -14/2 = -7
x = -7
So, only one answer/solution
Subtract 7 from 43. which equals 36. then find the square which is 6.
