Solución 1: 2(x) + 3(y) = 80
solución 2: 3(x) + 2(y) = 70
3(y) + 2(x) = 80
2(y) + 3(x) = 70
2y = -3x + 70
y = -3x÷2 + 35
2x + 3(-3x÷ 2+35) = 80
-5x÷2 = -25
-5x = -50
5x = 50
x-intercept: 10
x = 10
y = -3x÷ 2+35
y = -(3÷2)(10)+35 = 20
x-interpcet: 10
y-intercept: 20
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
solución: x - 8y = 0
solución x + 4y = 480
-8y + x = 0
4y + x = 480
x-intercept (solución 2)
x = -4x + 480
x-intercept (solución 1)
4y + 180 - 8y = 0
-12y = 480
y-intercept: 40
x-intercept: 320
Buena Suerte!
Answer: x=−3 or x=−5
Step-by-step explanation:
Step 1: Factor left side of equation.
(x+3)(x+5)=0
Step 2: Set factors equal to 0.
x+3=0 or x+5=0
x=−3 or x=−5
