2x+a=p 2x=p-a x=.5p-.5a
4+ X equals 2X. Subtract X from both sides. Four equals X
You cannot solve one equation in two unknowns.
2x+3 = 9x 3 = 9x-2x = 7x 7x = 3 x = 3/7
If: x+1+2x = 1x+5 Then: x = 2
it equals 13X.
x = 4 and y = 0
x = 3 and y = 3 Form a simultaneous equation and solve by elimination.
X = 0 (zero) Y = -1 (neg 1)
Yes and it works out that x = 3 and y = 4
2x + 2x + 146 + 26 = 172 4x + 172 = 172 4x = 0 x = 0
You need three independent equations to solve for three unknown variables.
22+2x = 37+6+x 2x-x = 37+6-22 x = 21
i guess it is y-2x=2 u can use this equation for a graph
