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
X equals five. hope this helps, and have a very brainly day!

In equation form: x=5 y=10
Explanation
Solve for the first variable in one of the equations (y=x+5), then substitute the result in the other equation.
Answer:
QR = 13.3
Step-by-step explanation:
We solve using Pythagoras Theorem
c² = a² + b²
RP² = PQ² + QR²
QR² = RP² - PQ²
QR = √RP² - PQ²
RP=15
PQ=7
QR = √15² - 7²
QR = √(176)
QR = 13.266499161
Approximately = 13.3
Therefore, the length of QR = 13.3
