Question

258x+2x-80=700, 50x+40x=540

Answer 1

1.

$258 \times x+2 \times x-80=700 \\ 260 \times x - 80 = 700 \\ 260 \times x = 700 + 80 \\ 260 \times x = 780 \\ x = 780 \div 260 \\ x = 3$

2.

$50 \times x+40 \times x=540 \\ 90 \times x = 540 \\ x = 540 \div 90 \\ x = 6$

Answer 2

To solve the equations, let's simplify and solve them step-by-step:

1. 258x + 2x - 80 = 700

Combine the x terms:

260x - 80 = 700

Now, isolate the x term:

260x = 700 + 80

260x = 780

Now, divide by 260 to find the value of x:

x = 780 / 260

x = 3

So, the solution for the first equation is x = 3.

2. 50x + 40x = 540

Combine the x terms:

90x = 540

Now, divide by 90 to find the value of x:

x = 540 / 90

x = 6

So, the solution for the second equation is x = 6.

Thus, the solutions for the given equations are:

x = 3 and x = 6.
