Answer:x=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4−3x=8−4x
4+−3x=8+−4x
−3x+4=−4x+8
Step 2: Add 4x to both sides.
−3x+4+4x=−4x+8+4x
x+4=8
Step 3: Subtract 4 from both sides.
x+4−4=8−4
x=4
Answer:
D.4
Step-by-step explanation:
The y-intercept is where the line crosses the y-axis. This line crosses the y-axis at 4, or the point (0,4) so the y-intercept would be 4.
Answer:
a=7
Step-by-step explanation:

-35 = -5a
Divide by -5
-35/-5 = -5a/-5
7=a
