Question

Y-32=-5/4(x-32) math

Answer 1

Answer:

x=3 y=4

Step-by-step explanation:

x+y=7; x + 2y =11

step: solve x + y = 7 for x:

x + y+ -y =7 + -y (add -y to both sides)

x = -y + 7

step: substitute -y + 7 for x in x + 2y =11:

x + 2y = 11

-y + 7 + 2y = 11

y + 7 =11(simplify both sides of the equation)

y + 7 + -7 = 11 + -7 (add -7 to both sides)

y = 4

step: substitute 4 for y in x = -y + 7:

x = -y +7

x = -4 + 7

x = 3 (simplify both sides of the equation)
