Solve the system of equations by substitution * + y=44 y=10x

X + y = 44

y = 10x

To solve this system by substitution, substitute 10x for y into the top equation.

x + y = 44

x + 10x = 44

11x = 44

x = 4

To find y, substitute 4 for x into either of the original equations; I'll use the bottom equation.

y = 10x

y = 10 (4)

y = 40

Lastly, substitute the x - and y-values into both original equations to check work.

x + y = 44

4 + 40 = 44

44 = 44

y = 10x

40 = 10 (4)

40 = 40

Answer:

x = 4; y = 40

(4, 40)
