Is 60-2x equals to 70-4x what is x?
60-2x = 70-4x 60-2x+2x = 70-4x+2x 60 = 70 +2x 60-70 = 70 + 2x - 70 -10 = 2x x = -10/2 = -5
4x - y equals 32y equals -2 x plus 70?
4x-y=32y=-2x+70 Try rearraging it. If they're all equal, then the order does not matter.2x+70=4x-y=32y-4x,-4x,+y,+y-2x+70=33y-x+35=33y
Solve X -2x plus 10 plus 4x equals to 70?
x - 2x + 10 + 4x = 70 Combine like terms: 3x + 10 = 70 Subtract 10 from both sides: 3x = 60 Divided both sides by 3: x = 20
2x equals 4x-70 solve for x?
2x = 4x - 70; it is easiest to first get rid of a 2 factor, so x = 2x - 35. subtract 2x from both sides, getting -x = -35. multiply both sides by -1, getting x = 35. Then, to check, plug the numbers back in. 2(35) = 4(35) - 70; 70 = 70.
60 percent of what equals 42?
42 is 60% of 70

What number when 130 is added to it equals 60 more than 2 times the number?
Let the number be x Then: x + 130 = 2x + 60 → 2x - x = 130 - 60 → x = 70 The number is 70.
60 percent of what equals 42?
42 is 60% of 70
EO equals 2X minus 20 and OC equals 70 minus X solve for X?
40
4x-5y equals 20 equals x-3y equals 10?
4x-5y=20 x-3y=10 becomes x=3y-10 plug that into the first equation: 4(3y-10)-5y=20 12y-40-5y=20 7y=60 y=60/7 If x=3y-10, then x=3(60/7)-10 x=180/7 - 70/7 x=110/7
What does -70 - plus 60 equals?
-10
What is the answer to 13x-2y equals 70 and 2x-2y equals 4 using the method of substitution?
i am guessing here that this is what you mean as it involves substitution: 2x-2y = 4 therefore -2y = 4 - 2x Sub the above line into the first equation gives: 13x - 2x +4 = 70 11x = 66 x=6 then sub in x 13(6) - 2y = 70 78 - 2y = 70 y=4 Yep, this is the exact same as simultaneous equations
How do you solve 4x plus y equals 70?
Solve for what? Do you want to rearrange the equation for y to be a function of x? y = 70 - 4x Do you want to rearrange it as a function of y? x = (70 - y) / 4 You'll need to be more specific in exactly what you want done.
What is x if 10x plus 22 plus 4x plus 70 equals 180?
x = 6 and 2/7
