Find a variable with equal or opposite coefficients, if equal then subtract the equations but if opposite then add, solve one variable equation left, and then substitute known variable into other equation and solve
Answer:
w = 5 , w = -5
Step-by-step explanation:
w^2 = 25
Take the square root of each side
sqrt(w^2) = ± sqrt(25)
w = ±5
Simplify both brackets, this equals 22 + 10x - 17 + 5x
Simplify further and you get 15x + 5
