Question

53×(х-9_1)=3975; (к+2958)÷87=134 решить

Answer 1

(К+2958):87=134
К+2858=134×87
К+2958=11.658
К=8700
(8700+2958):87=134
134=134

Answer 2

To solve the first equation:

53(x - 91) = 3975

We can start by simplifying the left side by distributing the 53:

53x - 53(91) = 3975

Then, we simplify further by performing the multiplication:

53x - 4823 = 3975

Next, we isolate the variable x by adding 4823 to both sides:

53x = 8798

Finally, we solve for x by dividing both sides by 53:

x = 166

Therefore, the solution to the first equation is x = 166.

To solve the second equation:

(k + 2958) ÷ 87 = 134

We can start by multiplying both sides by 87 to isolate the parentheses:

k + 2958 = 11658

Next, we isolate the variable k by subtracting 2958 from both sides:

k = 8700

Therefore, the solution to the second equation is k = 8700.
