It depends.
If you meant 8x-4=3x+1 then:
5x=5
x=1
But if you meant 8(x-4)=3(x+1) then:
8x-32=3x+3
5x=35
x=7
You would need to know what a is equal to in order to calculate this equation.
Yes that is correct
7
Technically there are no variables in this equation, as 47 minus 25 is equal to x (22)
y= 131127.691.
-6 when you multiply two minus numbers the minus signs cancel each other out so -12 * -6 = 72
The required equation is: -7x = 63
x = 4 and y = 7
3 and the solution is x = -5 and y = -3 When subtracting the equations remember that a - - is equal to a + So: - 6x - - 6x = 0 Also remember that a minus times a minus that the product is always a plus.
In the equation 5n-11=4n+20, n is equal to 31.
you need to find out what can you multiply by 5 minus 2 will equal 13. so x=3
Good work ! Did you have a question you wanted to ask ?
