36
Step-by-step explanation:
5x-6+3x+90=180
8x+84=180
8x=96
x=12
Plug it in to 3x
3x12=36
Answer:
x=-24
Step-by-step explanation:
1. but first multiply both sides by 3
x+21= -3
2. then move the constant to the right.
x= -3-21
3. calculate the difference
x= -24
hope this helps you!!!!

Venus- 243 / 1 , 729 / 3
Answer:
y = 2x - 3
Step-by-step explanation:
to do this problem, we will use the following formula to find the slope of the line
(y2 - y1) / (x2 - x1)
(1,5) (2,7)
(7 - 5) / (2 - 1)
2 / 1
2 = m
next, we will substitute the slope and one of the points into the slope-intercept form (y = mx + b) and solve for b to find the y-intercept
y = mx + b
7 = (5)(2) + b
7 = 10 + b
-3 = b
finally, we put it all together into one equation
y = 2x - 3
