Hello!
We can solve this system using substitution.
Since y = -3x + 5, we can substitute this into the following equation:
5x - 4(-3x + 5) = -3
Simplify:
5x - 4(-3x) - 4(5) = -3
5x + 12x - 20 = -3
Combine like terms:
17x - 20 = -3
Add 20 to both sides:
17x = 17
x = 1
Substitute to find y:
y = -3(1) + 5
y = -3 + 5
y = 2
Solution: (1, 2)

Answer and Step-by-step explanation:
We are given a linear pair. The angles of a linear pair add up to 180.
<u>To find x, add the two angles together and equal it to 180, then solve for x.</u>
126 + x + 23 = 180
<u>Simplify.</u>
149 + x = 180
<u>Subtract both sides of the equation by 149.</u>
x = 31
<u>x = 31 is the answer.</u>

Simplifying
3x + 7y = 28
Solving
3x + 7y = 28
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7y' to each side of the equation.
3x + 7y + -7y = 28 + -7y
Combine like terms: 7y + -7y = 0
3x + 0 = 28 + -7y
3x = 28 + -7y
Divide each side by '3'.
x = 9.333333333 + -2.333333333y
Simplifying
x = 9.333333333 + -2.333333333y
Answer:
b = 5
Step-by-step explanation:
Whatever you do to one side, you must do to the other side in order to make the equation stay true.
1. Subtract 22 from both sides.
-3b + 22 - 22 = 7 - 22
-3b = -15
2. Divide both sides by -3.
-3b/-3 = -15/-3
b = 5
^ That's the final answer!
