Answer:
2x-y=-1
Step-by-step explanation:
y + 9 = 2(x + 5)
y + 9 = 2x + 10 [distribute]
y = 2x + 1 [subtract 9 from both sides]
y - 2x = 1 [subtract 2x from both sides]
-2x + y = 1 [put x first]
2x - y = -1 [multiply by -1 to make x coefficient positive]
Answer:
x=6
Step-by-step explanation:
1 Add 44 to both sides.
2x=8+42x=8+4
2 Simplify 8+48+4 to 1212.
2x=122x=12
3 Divide both sides by 22.
x=\frac{12}{2}x=
2
12
4 Simplify \frac{12}{2}
2
12
to 66.
x=6x=6
