Answer:
x = 3
Explanation:
Given
19x - 5 = 7 + 15x ( subtract 15x from both sides )
4x - 5 = 7 ( add 5 to both sides )
4x = 12 ( divide both sides by 4 )
x = 3
As a check
Substitute x = 3 into the equation and if both sides are equal then it is the solution.
left side = (19 × 3) - 5 = 57 - 5 = 52
right side = 7 + (15 × 3) = 7 + 45 = 52
Hence x = 3 is the solution
