2x - 2y = 12 (1)
1x + 5y = 34 (2)
x + 5y = 34 subtract 5y to both sides
x = 34 - 5y (3)
Substitute 34 - 5y for x into the first equation
2x - 2y = 12
2(34 - 5y) - 2y = 12
68 - 10y - 2y = 12
68 - 12y = 12 subtract 68 to both sides
-12y = -56 divide by -12 to both sides
y = 4.666666667
Substitute 4.7 for y into the third equation
x = 34 - 5y
x = 34 - 5(4.7)
x = 34 - 23.33333333
x = 10.66666667
Check:
i think you mean:1x+2y=5 1x+4=6
Simplifying x2 + -2x + -63 Reorder the terms: -63 + -2x + x2 Factor a trinomial. (-7 + -1x)(9 + -1x) Final result: (-7 + -1x)(9 + -1x)
7 + 1x + 5 = 12 + x
It can be simplified to: x-5y
The expression x2 + 1x - 12 can be factored out as (x - 3)(x + 4)
i think you mean:1x+2y=5 1x+4=6
4x+3x-1x = 12 Collect like terms: 6x = 12 Divide both sides of the equation by 6 to find the value of x: x = 2
-.6x+.5x+9=-3 -.1x=-12 x=120
its answer is probably -4.4 best of luckk!!!!!:)

7 + 1x + 5 = 12 + x
If: x+1+2x = 1x+5 Then: x = 2
1x-5x = -4x But since you had the absolute value symbols surrounding it, change it to positive; so the answer is: 4x
1x - 14x = -13x. you cant subtract the four because it does not have an x on it so the answer would be -13x -4
It can be simplified to: x-5y
The expression x2 + 1x - 12 can be factored out as (x - 3)(x + 4)
First add coefficients: * 1x + 1x = 2x Second add the other values: * 4 + 5 = 9 Put it all together!: * 1x + 1x + 4 + 5 = 2x +9 * 2x + 9
