6x+2y=4 gives y=2-(1/3)x
5x+3 = x+4 5x-x = 4-3 4x = 1 x = 1/4 Thats not even close to how you solve it. First of all the equation is written 5^(x+3)=x+4. Simple Logarithms are needed to solve.
2x2-x-3 = 0= 4 - x - 3 = 0= 1 - x = 0= 1 = xTherefore x = 1
x = 7 7-4/3 x 7 = 1/7 3/21 = 1/7
x - 2y = -4 2x - y = 1 To solve this system of equations, I used matrices, and got x = 2 and y = 3.
2x2+1x-3=0 4+x-3=0 x+1+0 x=-1 is your final answer
n=-4/3
4
4 + 4 +1
1
x=-1 ^ how do you know?
3 plus 1 plus 4 equals 8
