Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
A haircut costs $31
Coloring hair costs $93
Step-by-step explanation:
h = haircut
c = color
First equation: 1h + 2c = 217
Second equation: 2h + 1c = 155
Solve using elimination:
First, multiply both the equations so that they cancel the h's out:
First equation:
-1(2h + 1c = 155)
-2h - 1c = -155
Second equation:
2(1h + 2c = 217)
2h + 4c = 434
Then, put the equations together, and solve:
2h + 4c = 434
-2h - 1c = -155
3c = 279
c = 93
Find h:
2h + 1c = 155
2h + 1(93) = 155
2h + 93 = 155
2h = 62
h = 31
Hope this helped!
To find the slope and y-intercept, you need to get the equation into slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
-12x - 4y = 10
+12x +12x
-4y = 12x + 10
/-4 /-4
y = -3x - 10/4
The x access is horizontal and the y access is vertical. you start from 0 then go to your number on the x access from there go up on the y access.<span />
