Question

2×(х+5)+7×(3х-7)=53

Answer 1

2*(х+5)+7*(3х-7)=53
2*х+5+7*3х-7=53
2х+10+21х-49=53
2х+21х=53-10+49
23х=92
х=92:23
х=4

Answer 2

2(x+5)+7(3x-7)=53

2x+10+21x-49=53

23x=92

x=92/23

x=4

Answer 3

To solve the equation 2x + 5 + 7(3x - 7) = 53, follow these steps:

Step 1: Distribute the multiplication on the left side of the equation. 2x + 5 + 21x - 49 = 53

Step 2: Combine like terms on the left side of the equation. 23x - 44 = 53

Step 3: Isolate the variable term (23x) by moving the constant term (-44) to the other side of the equation. 23x = 53 + 44

Step 4: Simplify the right side. 23x = 97

Step 5: Solve for x by dividing both sides by the coefficient of x (23). x = 97 / 23

Step 6: Simplify the result (if possible). x ≈ 4.2174 (rounded to four decimal places)

So, the value of x that satisfies the equation is approximately x ≈ 4.2174.
