Answer:
x = 1
Step-by-step explanation:
First simplify and get 3x + 3 = x + 5
Then subtract x from both sides and get 2x + 3 = 5
Then subtract 3 from both sides and get 2x = 2
Divide both sides by 2 and get x = 1
Answer:
y = 3
Step-by-step explanation:
substitute the x in 2x - y = 7 by x = 3y - 4 and then solve
2(3y - 4) - y = 7
<em>Distribute the 2 into the parenthesis</em>
6y - 8 -y = 7
<em>combine like terms</em>
5y - 8 = 7
<em>add 8 on both sides</em>
5y = 15
<em>divide by 5 on both sides to isolate the y-value</em>
y = 3
