5x-3y=9
2x+3y=19
simplify by substitution method
Answers
Answer:
5x - 3y = 9
5x = 3y + 9
X = 3y + 9/5
in other equation put the value of x
2 ×( 3y + 9/5 ) + 3y = 19
6y + 18/5 + 3y = 19
9y = 19 - 18/5
9y = 95 - 18/5
9y = 77/5
y = 77/5 × 9
y = 138.6

I will say you both and hope it helps!
1. X = 1.8 + 0.6y 2. X = 9.5 + 1.5Y
Step-by-step explanation:
1. Simplifying
5x + -3y = 9
Solving
5x + -3y = 9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
5x + -3y + 3y = 9 + 3y
Combine like terms: -3y + 3y = 0
5x + 0 = 9 + 3y
5x = 9 + 3y
Divide each side by '5'.
x = 1.8 + 0.6y
Simplifying
x = 1.8 + 0.6y
2. Simplifying
2X + 3Y = 19
Solving
2X + 3Y = 19
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-3Y' to each side of the equation.
2X + 3Y + -3Y = 19 + -3Y
Combine like terms: 3Y + -3Y = 0
2X + 0 = 19 + -3Y
2X = 19 + -3Y
Divide each side by '2'.
X = 9.5 + -1.5Y
Simplifying
X = 9.5 + -1.5Y
