Answer:
3x-10=56
3x=56+10
3x=66
3x/3 = 66/3
x=11
79-y=2x
79-y=2(11)
79-y=22
79-22=y
y=57
therefore x=11 and y=57
3x-10=56
79-y=2x so y=-2x+79
(Solve 3x−10=56 for x):
3x−10=56
3x−10+10=56+10 (Add 10 to both sides)
3x=66
(Divide both sides by 3)
x=22
(Substitute 22for x in y=−2x+79):
y=−2x+79
y=(−2)(22)+79
y=35 (Simplify both sides of the equation)
Answer:
x=22 and y=35
