After solving
we get value of x: 
Step-by-step explanation:
We need to solve the equation
to find value of x
Solving

Adding -e on both sides


Multiply both sides by dx

Divide both sides by M-e

Divide both sides by d

So, After solving
we get value of x:

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)
