Answer:
x=4
Step-by-step explanation:
5x + 33 = 18x-30 + 11
Add the numbers
5x + 33 = 18x-19
Subtract 33 from both sides of the equation
5x + 33-33 = 18x-19-33
5x=18x-52
Subtract 18x from both sides of the equation
5x-18x = 18x-52-18x
-13x = -52
-13x/-13 = -52/-13
x=4
X - 3y = -8
x + 3y = 8
--------------- Add the equations
2x = =
x = 0
Plug zero back in to either equation and solve for y.
x - 3y = -8
0 - 3y = -8
-3y = -8
divide both sides by -3
y = 8/3
(0, 8/3)
ONE SOLUTION
Answer:
y = 5/3
x = 8/3
Steps:
y = x - 1
2x + y = 7
Substitute y = x-1
(2x + x - 1 = 7)
Simplify: 3x - 1 = 7
Isolate x: 3x - 1 = 7: x=8/3
Plug the valuse of x into the other equation (y = x- 1): y = 8/3 - 1
8/3 - 1 = 5/3
y = 5/3
y = 5/3, x = 8/3
