Answer:

x-value is 4

Step-by-step explanation:

2x-3y=-1

3x+4y=24

We can solve the equation by eliminating y

We multiply the first equation by 4 and the second by 3

4(2x-3y=-1 )

3(3x+4y=24)

8x -12y = -4

9x +12y = 72

Then we add the two equations;

8x -12y = -4

9x +12y = 72

17x = 68

  x = 4

Thus the x-value is 4

<h3>Hello there!</h3>

In this question, we're solving for t in the inequality.

Solve:

2 > -3t - 10

Add 10 to both sides

12 > -3t

Divide both sides by -3, also flipping the inequality since you're dividing by a negative

-4 < t

The t must be in the left side, so we would flip the whole equation.

t > -4

<h3>Answer: t > -4</h3><h3>I hope this helps!</h3><h3>Best regards,</h3><h3>MasterInvestor</h3>

8\frac{3}{8}= \frac{67}{8}

2\frac{1}{2} = \frac{5}{2} = \frac{20}{8}

\frac{67}{8}-  \frac{20}{8} = \frac{47}{8} =5 \frac{7}{8} in

−6x + 14 &lt; −28 OR 9x + 15 ≤ −12. solve for x.
sasho [114]

Answer:

x>7 or x ≤ -3

Step-by-step explanation:

Solving the 1st inequality

-6x +14 < -28 --------------- (Collect like terms)

-6x < -28 - 14

-6x < - 42 -------------------- (Divide both sides by -6)

Note: If you decide an inequality expression by a negative value, the inequality sign changes)

-6x/-6 > -42/-6

x > 7

Solving the 2nd inequality

9x + 15 ≤ −12 ----------- (Collect like terms)

9x ≤ −12 - 15

9x ≤ −27 ------------------(Divide both sides by 9)

9

9x/9 ≤ −27/9

x ≤ -3

Bring both results together, we get

x>7 or x ≤ -3

The final result is complex (i.e. can't be combined together).
