Maggie =x
brother = 2x-3
x+2x-3= 24
27 /3= 3 x/3
x= 9 years
Answer:
Jasmine ran last week 37.2 miles
Step-by-step explanation:
Let
x ----> number of miles Rob ran last week
y ----> number of miles Jasmine ran last week
we know that
x=y-27.2 ----> equation A
x=10 ----> equation B
Substitute equation B in equation A and solve for y
10=y-27.2
y=10+27.2
y=37.2 miles
Y+1 = -2x+2 (distribute)
Y=-2x + 1 (isolate y)
