number - n

Twice a number - 2n

Seven times the number - 7n


2n = 7n +35

7n-2n = -35

5n = -35

n = - 7


Check:

2(-7) = 7(-7) +35

-14 = -49 + 35

-14 = -14 True


The number is (- 7).

1 - 3x = 3x + 1 solve for x
lakkis [162]

Answer: x = 0

Step-by-step explanation:

1 - 3x = 3x + 1

then add 3x on both sides

1 = 6x + 1

then subtract 1 on both sides

0 = 6x

then divide by 6 on both sides

0 = x

so x = 0

What is the value of x in the equation 4x+8y=40 when y=0.8
GREYUIT [131]
Substitute in 0.8 for y.

4x+8y=40 \\ \\ 4x + 8(0.8) = 40 \\ \\ 4x + 6.5 = 40 \\ \\ 4x = 40 - 6.4 \\ \\ 4x = 33.6 \\ \\ x = 8.4 \\ \\

The final result is: x = 8.4.
