The answer or average is 15
3x + 2y = 12
5x - 2y = 4
When adding the 2 equations, the y's will cancel.
8x = 16 divide both sides by 8.
X= 2
Slope = rise/run or m = (y₂-y₁)/(x₂-x
Slope of line passing through A(8,8) and B(4,6)→
m = (6-8)/(4-8) = (-2)/(-4) = 1/2
m = 1/2
Assuming you need to solve for x:
-6(x + 6) - 10 = -2(5 + 4x)
start by distributing your numbers outside the front of your parentheses:
-6x - 36 - 10 = -10 - 8x
then combine like terms:
-6x - 46 = -10 - 8x ... add 10 to both sides (which technically could have cancelled out in the step prior, but regardless)
-6x - 36 = -8x ... add 6x to both sides
-36 = -2x ... divide both sides by -2
x = 18
