<u>x = 8</u>
<u>y = 3</u>
x = 5y - 7
x + y + 1 = 12
Because we have a value for x, we can use it in the second equation to find the value of y.
5y - 7 + y + 1 = 12
<em><u>Combine like terms</u></em>
6y - 6 = 12
<em><u>Add 6 to both sides.</u></em>
6y = 18
<em><u>Divide both sides by 6.</u></em>
y = 3
Now that we have a value for y we can place it back in the equation to find the value of x.
x + 3 + 1 = 12
<em><u>Subtract 4 from both sides.</u></em>
x = 8
X - 20 = 24
Add 20 to both sides
x = 24 + 20 = 44
Answer:
x = 2
Explanation:
2(x+2)-5=3(x-1)
1) Use distributive property (multiply the 2 by x+2 and the 3 by x-1)
2x+4-5=3x-3
2) Combine like terms
2x-1=3x-3
3) Subtract 2x on both sides
-1=x-3
4) Add 3 on both sides
2=x
