Answer:
x=8
Step-by-step explanation:
I am assuming you need to find which x value fits this.
So set the two equations equal to each other
158=70+11x, subtract 70 from both sides
88=11x, now, divide by 11 to get x by itself,
8=x, to find these answers, use a calculator or any other method you want.
Equation of a line in standard form is Ax + By = C
A is a pos. integer and B + C are integers
1) multiply all terms in the equation by 2
2y = x - 6
2) subtract 2y from both sides
2y - 2y (cancelled out) = x - 2y - 6
x - 2y - 6 = 0
3) add 6 to both sides
x-2y = 0 +6 (-6 and +6 cancel out)
therefore,
x - 2y = 6
is the equation in standard form
Equation: 4x+15=31
I have included a picture of my work since explaining might be difficult but the way I solved this if the beginning of algebra and I hope it makes sense.

the six(6) muffins plus the $3 she saved
Answer:
C
Step-by-step explanation:
Δ AQP and Δ ACB are similar triangles, thus the ratios of corresponding sides are equal, that is
=
( note that AC = 3 + 6 = 9 ), substitute values
=
( cross- multiply )
3BC = 40.5 ( divide both sides by 3 )
BC = 13,5 cm → C
