<u><em>x=8 is the correct answer.</em></u> First you had to subtract by 5 from both sides of equation, and it gave us, \frac{x}{4}+5-5=7-5. And then simplify, and it gave us, \frac{x}{4}=2. Then you can multiply by 4 from both sides of equation, and it gave us, \frac{4x}{4}=2*4. And finally simplify, and it gave us the answer is 2*4=8, or <u><em>x=8 is the correct answer.</em></u> Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

Solve the system of linear equations by substitution.<br><br> y = 2x + 8<br> y = -2x
posledela

Answer:

(- 2, 4 )

Step-by-step explanation:

y = 2x + 8 → (1)

y = - 2x → (2)

substitute y = 2x + 8 into (2)

2x + 8 = - 2x ( add 2x to both sides )

4x + 8 = 0 ( subtract 8 from both sides )

4x = - 8 ( divide both sides by 4 )

x = - 2

substitute x = - 2 into (2)

y = - 2(- 2) = 4

solution is (- 2, 4 )
