1. Subtract the second equation from the first and solve for y: 0 - 4y = -20 => y=5
2. Substitute y=5 into one of the equations and solve for x: 4x - 3(5) = -3 => 4x = 12 => x=3
So the solution is (x, y) = (3, 5)
Answer: x1 = -2, x2 = 3/4
Step-by-step explanation:
4x^2 + 5x -6 = 0
4x^2 + 8x -3x -6 = 0
4x(x+2)-3(x+2)=0
(x+2)(4x-3) = 0
x+2 = 0: x = -2
4x-3 = 0: x = 3/4
Answer:
Step-by-step explanation:
5x + 10 - 3x = 2x - 10
2x + 10 = 2x - 10
0x = -20
no solution
Answer:
X = 56
Step-by-step explanation:
Subtracting 169 degrees from a straight line (180 degrees) gives you 11 degrees. with this information you can add 11 and 114 to get 124. Then you can subtract that amount from 180 (the measure of any triangle) and get your answer which is 56. I hope this helped!
