Answer:
x = 18
Step-by-step explanation:
Twice a number becomes 2x, decreased by 4 becomes -4, and combined those terms equal 32.
2x - 4 = 32
2x - 4 + 4 = 32 + 4 (isolate the variable)
2x = 36
x = 18

Answer:
2+-2+-2=-2
Step-by-step explanation:
2x + y = 5
x − 2y = 10
y = 5 − 2x
x − 2(5 − 2x) = 10
x − 10 + 4x = 10
5x − 10 = 10
<em>add 10 to each side</em>
<em>5x-10+10 = 10 + 10</em>
<em>5x=20</em>
5x = 0 <em>this is the error</em>
He needs to add 10 to each side
