For the functions below, calculate the indicated function values. (1 Point) f(x) = x 8(x) = 5x - 12 h(x) = x2 + 4x - 7 Find g (a + b)​

Use the linear combination method to solve the system of equations. explain each step of your solution. if steps are not explained, you will not receive credit for that step. 2 + 9 = −26 −3 − 7 = 13
