Set 4x equal to x+30 and solve.
prisoha [69]

Answer:

x = 10

Step-by-step explanation:

1) Subtract x from both sides.

4x − x = 30

2) Simplify 4−x to 3x

3x = 30

3) Divide both sides by 3

x = \frac{30}{3}

4) Simplify \frac{30}{3} to 10

x = 10

HELP PLEASE I WILL GIVE BRAINLIEST AND 35 POINTS!!!!!!!!!!!!!!!!!!!!!!!Which statements are true about the ordered pair (−1, 5)
murzikaleks [220]
The ordered pair (-1,5) is a solution to the system because it makes both equations true.

1) x+y=4
2) x-y=-6

1) -1 + 5 = 4
    5-1 = 4   you can switch the order to make it easier to understand
        so
        4 = 4

2) -1 - 5 = -6
     -1 + -5 = -6 you can change the sign in the middle and make y - 
          so
        -6 = -6

Same side.  Locate -3.9 on the number line.  Then -0.99 is to the right of -3.9, with both numbers being on the same side (that is, on the left side) of zero.
