7/8a=42
a=42*8/7 (times both sides by 8/7 to cancel the fractions)
a=48
Hello
-4x + 11y = 15
x = 2y
Ok, we need to solve x = 2y for x
Lets start by substitute 2y for x in -4x + 11y = 15
-4x + 11y = 15
-4(2y) + 11y = 15
-8y + 11y = 15
3y = 15
Divide both sides by 3
3y/3 = 15/3
Y = 5
Again, substitute 5 for y in x= 2y
x = 2y
x = 2(5)
x = 10
Final answer : X = 10 and y = 5
Good luck!
Y=x-3 it's one of many equations
