Question

Rewrite the equation in Ax+By=C Use integers for A, B, and C. y+1=6(x+4)

Answer 1

So the problem is asking you to write y + 1 = 6(x+4) in the form Ax+By=C. A lot of this will involve algebra and moving the numbers around until you have it in the right form.

1) Start by distributing 6 to x and 4 on the right using the distributive property. 
y + 1 = 6(x+4) 
y + 1 = 6x + 6(4)
y + 1 = 6x + 24

2) Move everything with the variables x or y onto the left side using addition or subtraction. Move everything else onto the other side. This means subtracting the 6x from both sides and subtracting 1 from both sides. Simplify:
y + 1 = 6x + 24
y - 6x + 1 = 24
y - 6x = 24 - 1
y - 6x = 23

3) Put your equation in the form Ax+By=C. 
y - 6x = 23
-6x + y = 23

-------

Answer: -6x + y = 23

A = -6, B = 1, C = 23
