2x^2 + 8x + 3 = 0
y=-10x-4
2x + y = 25 x + y = 14 Subtract second equation from the first: x = 11 Substitute this value of x in the second equation: 11 + y = 14 ie y = 3
3
Yes, because the equation is linear, there is only one solution:4x - 3 = 12 +2x4x - 2x = 12 + 32x = 15x = 7.5There is no other solution

Do you need this equation factored or? 2x+3=x+4?
y=-2x+3 is an equation. It does not have an answer. If the question is "what if y=0?" then the answer is x=3/2.
2x + 3 = 72x = 4x = 2
It equals to the equation of a straight line.
It is the equation of a sraight line.
2x + 3 = 6 2x = 3 x = 3/2 = 1.5
An equation where x equals 3.
An equation where x = 3
It is an equation and the value of x is 2
It is an equation and the value of x is 1
2x-3=x+2 2x-x=2+3 x=5
