this goes with steps and answer
Step-by-step explanation:
hope this helped!
Y+7=3x
6x-2y=12
y=3x-7
6x-2(3x-7)=12
6x-6x+14=12
14=12
No solution
450= 175+25x
(let x stand for how many hours of lessons dakota can afford)
Step 1: Simplify both sides of the equation.
450=25x+175
Step 2: Flip the equation.
25x+175=450
Step 3: Subtract 175 from both sides.
25x+175−175=450−175
25x=275
Step 4: Divide both sides by 25.
25x25=27525x
x=11
Dakota can afford 11 hours of lessons.
