Slope intercept form = Y = Mx + B
15 = -3y + 21x
3y = 21x - 15
Y = 21/3 X - 15/3
Y = 7x - 5 = SI Form
Solve for x.
First multiply everything in the parenthesis by 3.
12 + 12x = 12 + 12x
There is an infinite amount of solutions.
Hope this helps!
B:S = 4x:3x
4x - 3x = 3
x = 3
They were 12 & 9.
Add 5 to that.
So he’s now 17 and she’s 14
