If a^b=17 and a-b =1 then a,b are |
|
Answer» Answer: if a^b=17 and a-b =1 then a,b are We are given a system of two linear, simultaneous equations in two unknowns, a and b: a+ b = 19 and a - b = 1. To solve for the UNKNOWN a, we'll use the Elimination Method (Addition/Subtraction Method) as follows to get rid of the variable b: Adding the two equations, we get: a + b = 19 a - b = 1 --------- 2a + 0 = 20 2a = 20 (2a)/2 = 20/2 (2/2)a = 20/2 (1)a = 10 a = 10 The student should continue using the Elimination Method(Addition/Subtraction Method) by subtracting equation a - b = 1 from a + b = 19 to see that b = 9, and then substituting a = 10 and b = 9 into BOTH of the given equations to see that the ordered-pair solution (a, b) = (10, 9) makes BOTH equations true. 1K views View upvotes 1 Related Questions (More ANSWERS Below) |
