Solve -2*4-t*3=-15*(2*4)+42

$$- 2 \cdot 4 - t \cdot 3 = - 15 \times ( 2 \cdot 4 ) + 42$$

Solve for t

$$t = \frac{70}{3} = 23\frac{1}{3} \approx 23.333333333$$

Steps for Solving Linear Equation

Multiply -2 and 4 to get -8.

$$-8-t\times 3=-15\times 2\times 4+42$$

Multiply -15 and 2 to get -30.

$$-8-t\times 3=-30\times 4+42$$

Multiply -30 and 4 to get -120.

$$-8-t\times 3=-120+42$$

Add -120 and 42 to get -78.

$$-8-t\times 3=-78$$

Multiply -1 and 3 to get -3.

$$-8-3t=-78$$

Add 8 to both sides.

$$-3t=-78+8$$

Add -78 and 8 to get -70.

$$-3t=-70$$

Divide both sides by -3.

$$t=\frac{-70}{-3}$$

Fraction \frac{-70}{-3} can be simplified to \frac{70}{3} by removing the negative sign from both the numerator and the denominator.

$$t=\frac{70}{3}$$
