Question

800-х=198+142 , а+154=807-142​

Answer 1

-x=340-800
x=460

2.a+154=665
a=511

Answer 2

Let's solve the given equations:

1. 800 - x = 198 + 142

To solve for x, we can combine the numbers on the right side of the equation:

800 - x = 340

Now, let's isolate x by subtracting 800 from both sides:

-x = 340 - 800 -x = -460

To get rid of the negative sign, we multiply both sides by -1:

x = (-1) * (-460) x = 460

Therefore, the solution to the first equation is x = 460.

2. a + 154 = 807 - 142

To solve for a, we can combine the numbers on the right side of the equation:

a + 154 = 665

Now, let's isolate a by subtracting 154 from both sides:

a = 665 - 154 a = 511

Therefore, the solution to the second equation is a = 511.

To summarize:

• In the first equation, x = 460.
• In the second equation, a = 511.
