7a + 4 = 5a + 7 7a = 5a + 3 2a = 3 a = 3/2
It's a simple algebraic equation.If the value of 'a' is needed, it can be derived as follows:7a + 10 = 2aSubtract 2a from each side:5a + 10 = 0Subtract 10 from each side:5a = -10Divide each side by 5:a = -2
Add them together: 2a+5a = 7a
2a
7a-17 = 4a+1 7a-4a = 1+17 3a = 18 a = 6
