If you mean x+2y = -2 and 3x+4y = 6 then by solving the simultaneous equations by substitution x = 10 and y = -6
x+2y = 7 2y = -x+7 y = -0.5x+3.5
3x plus 2y can be expressed mathematically as (3x + 2y).
11x + 2y
If: 3x+2y = 5x+2y = 7 which is the same as 7 = 7 = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtracting equations: x = 0 Therefore by substitution: x = 0 and y = 3.5
If you mean x+2y = -2 and 3x+4y = 6 then the solutions to the equations are x = 10 and y = -6
If you mean x+2y = -2 and 3x+4y = 6 then by solving the simultaneous equations by substitution x = 10 and y = -6
i think you mean:1x+2y=5 1x+4=6
x+2y = 7 2y = -x+7 y = -0.5x+3.5
4x-2y+3x+2y When simplified: 7x
3x plus 2y can be expressed mathematically as (3x + 2y).
7+4xz+52xz+2y=7+56xz+2y
11x + 2y
If: 3x+2y = 5x+2y = 14 Then: 3x+2y = 14 and 5x+2y =14 Subtract the 1st equation from the 2nd equation: 2x = 0 Therefore by substitution the solutions are: x = 0 and y = 7
12x-4y+9z+2y =12x-2y+9z
3x+2y-5=0 3x+2y=5 Im lost im only 12 work out the rest hope i helped
If: 3x+2y = 5x+2y = 7 which is the same as 7 = 7 = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtracting equations: x = 0 Therefore by substitution: x = 0 and y = 3.5
