Infinite, both equations are equivalent and all possible solutions can be represented on the graph y = 4 - x
x equals 4
If x=4 then 2x+7 =
There are two solutions and they are: x = -1 and y = 3
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.

None. When these two equations are graphed, the two lines are parallel. Since they never intersect, there is no point that satisfies both equations.
3x+56 = 2x+4 3x-2x = 4-56 x = -52
0 = 2x^2 + 2x - 4 = 2(x^2 + x - 2) = 2(x-1)(x+2) Thus, there are two real solutions: x = 1 and x = -2
x2+10x+1 = -12+2x x2+8x+13 = 0 The solution: x = -4 + the square root of 3 or x = -4 - the square root of 3
Do you need this equation factored or? 2x+3=x+4?
x=-4
