Solve for x: 5x+7=3x−9.

Mathematics
1 answer:
ludmilkaskok [199]1 year ago
6 0

To solve for x in the given equation;

5x+7=3x-9

We start by collecting like terms, as follows;

5x-3x=-9-7

When a number crosses the sign of equality, the sign in front of it switches. Positive numbers becomes negative, and vice versa.

We would now have;

\begin{gathered} 5x-3x=-9-7 \\ 2x=-16 \\ \text{Divide both sides by 2;} \\ \frac{2x}{2}=\frac{-16}{2} \\ x=-8 \end{gathered}

ANSWER:

The answer is x = -8

Can anyone help me answer 4 and 5? Plzz
GaryK [48]
#4

Examine the relationship between y and x, waiting until later to examine the y-intercept.    For example:  If we look at B, and mult. x = 2 by 0.55, we get 1.10, which is not even close to the y = 6.5 given in the table.  If, however, we mult. 2 by 3.55, we get 7.10, which is not the same as the y = 6.5 given in the table, but is much closer than 1.10.

Also note that all y values in the table are positive, so a negative slope would be inappropriate.  That eliminates choices A and D.

Focus now on the remaining choices B and C.  Again, let x= 2 and determine the associated y value.  Which y value is closer to the table's 6.5?

B:  0.55(2) + 3.55 = 4.65 (relatively far away from the table's 6.5)

C:  3.55(2) - 0.55 = 6.55 (very close to the table's 6.5)

C is the correct answer.
