7+2(a+1)-3a=5a
we should first multiply 2 with the value in bracket
So,
7+2a+2-3a=5a
Now taking variable on L.H.S. and numeric value ON R.H.S.
2a-3a-5a=-2-7
-6a=-9
a=3/2

Simplifying
7 + 2(a + 1) + -3a = 5a
Reorder the terms: 7 + 2(1 + a) + -3a = 5a 7 + (1 * 2 + a * 2) + -3a = 5a 7 + (2 + 2a) + -3a = 5a
Combine like terms: 7 + 2 = 9 9 + 2a + -3a = 5a
Combine like terms: 2a + -3a = -1a 9 + -1a = 5a
Solving 9 + -1a = 5a
Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-5a' to each side of the equation.
9 + -1a + -5a = 5a + -5a
Combine like terms: -1a + -5a = -6a
9 + -6a = 5a + -5a
Combine like terms: 5a + -5a = 0 9 + -6a = 0
Combine like terms: 9 + -9 = 0 0 + -6a = 0 + -9 -6a = 0 + -9
Combine like terms: 0 + -9 = -9 -6a = -9
Divide each side by '-6'. a = 1.5
Simplifying a = 1.5
