Answer:
x = 17 y= -38
Step-by-step explanation:
x + y = -21
y = x - 55
It doesn't matter whether x or y is 55 less than the other right now.
<u>substitute for y:</u>
x + x - 55 = -21
<u>solve for x:</u>
2x = 34
x = 17
<u>solve for y:</u>
17 + y = -21
y = -38
Step 1: Simplify both sides of the equation.
x−7=15+3x
x+−7=15+3x
x−7=3x+15
Step 2: Subtract 3x from both sides.
x−7−3x=3x+15−3x
−2x−7=15
Step 3: Add 7 to both sides.
−2x−7+7=15+7
−2x=22
Step 4: Divide both sides by -2.
−2x/−2=22/−2
x=−11
