Solve -4-2/5+-12-1/4*20=-8+1/2*20

$$\frac{ -4-2 }{ 5 } + \frac{ -12-1 }{ 4 } \times 20= \frac{ -8+1 }{ 2 } \times 20$$

Verify

Solution Steps

Multiply both sides of the equation by 20, the least common multiple of 5,4,2.

$$4\left(-4-2\right)+5\left(-12-1\right)\times 20=10\left(-8+1\right)\times 20$$

Subtract 2 from -4 to get -6.

$$4\left(-6\right)+5\left(-12-1\right)\times 20=10\left(-8+1\right)\times 20$$

Multiply 4 and -6 to get -24.

$$-24+5\left(-12-1\right)\times 20=10\left(-8+1\right)\times 20$$

Subtract 1 from -12 to get -13.

$$-24+5\left(-13\right)\times 20=10\left(-8+1\right)\times 20$$

Multiply 5 and -13 to get -65.

$$-24-65\times 20=10\left(-8+1\right)\times 20$$

Multiply -65 and 20 to get -1300.

$$-24-1300=10\left(-8+1\right)\times 20$$

Subtract 1300 from -24 to get -1324.

$$-1324=10\left(-8+1\right)\times 20$$

Add -8 and 1 to get -7.

$$-1324=10\left(-7\right)\times 20$$

Multiply 10 and -7 to get -70.

$$-1324=-70\times 20$$

Multiply -70 and 20 to get -1400.

$$-1324=-1400$$

Compare -1324 and -1400.

$$\text{false}$$
